SPECIFICATION forming part of Letters Patent No. 353,506, dated November30, 1886,

Application filed April 520, 1886. Serial No. 199,522. (X0 model.)

To all ZU7L0772/ it may concern.-

Be it known that I, ARTHUR W. RUMSEY, of New Kiowa, in the county ofBarber and State of'Kansas, have invented a new and Improved Clevis, ofwhich the following is a full, clear, and exact description.

My invention relates to that class of draft devices known as clevisesand adapted for attachment to agricultural implements or other machinesor to vehicles, and has for its object to provide a simple, inexpensive,and effective clevis which may be quickly and easily connected to ordisconnected from the implement or machine and will not uncoupletherefrom accidentally.

The invention consists in certain novel fea tures of construction andcombinations of parts of the clevis, all as hereinafter fully describedand claimed. I

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in both the figures.

Figure 1 is a side View of my improved clevis, partly broken away and insection; and Fig. 2 is a bottom edge view of the clevis.

The clevis has four main partsa bar, A, a bar, B, a pin, 0, and aSpring, D.

The bar A hasa straight part, a, which-is the top of the clevis, and abent or curved part, a, which is the forward end of the clevis, and nearthe extremity of the part a is formed a slot, E, thus providing an endcrosspiece, e. The forward end of the bar B is provided with ahorizontally-ranging slot, F, into which the cross piece eof bar Apasses, while the end cross piece,f, of bar B enters theverticallyranging slot E of bar A, and whereby the parts A B will beloosely connected or linked together.

At the forward end and upper side of the slot F of bar B there is formedarecess,f, providing a shoulder at f, against which the end of thecross-piece e of bar A is adapted to lock, and the spring D, which isfixed at one end-to the bar B, hasat its other end an inbent eye orloop, (Z, which passes through a slot, 2), of the bar B and pressesagainst the cross-piece e to hold itin the recessf, and in front oftheshoulderf and thus hold the parts A B together, as shown in Fig. 1, whenthe pin 0 is engaged with the bar A, as next described.

The draftpin C is rigidly fixed in or to the back end of the bar B, andits extremity may be passed into a hole, G, made through the bar A, andnear its top the pin C is cut away to form a recess, 0, the endshoulders, 0 c of which pass above and below the bar A, when the bar Band pin O are moved backward after the pin is passed into the hole G, aswill be understood from Fig. 1 of the drawings.

A retaining-pin or cotter, H, may be passed through the pin 0, above thebar A, if preferred, to make the connections of the parts A B at theslots E F, as in Fig. 1, more secure.

It is obvious that if the pin H, when used, be removed, and thecross-piece c of barA be depressed against the tension of the spring Duntil the cross-piece escapes from the shouldcr f of bar B, the bar Band pin 0 then may be moved forward sufficiently to disengage theshoulders c c" from the back end piece, (6 of bar A, behind the hole G.and the pin 0 may be withdrawn from hole G as the bar B swings downwardon the cross-piece e of bar A, and as indicated in dotted lines in Fig.1, to allow the draft-pin C to be slipped into the draft'ring or behinda draft-bar of an agricultural implement or other machine or vehicle,whereupon, by swinging the bar B upward, the pin 0 may be entered intothe hole G, and the shoulders c 0* of the pin will engage above andbelow the end piece, a of bar A as the end crosspiece, e, of bar A isforced upward by the end (I of the spring D into engagement withthe'shoulder f of the bar B.

The spring D may be dispensed with when the pin H is used, as theshoulderf of bar B der, f, in said slot adapted to engage an endcross-piece, e, of bar A, and a pin, 0, held rigidly to bar B, andadapted to enter the hole G of bar A, and provided with a side recess,a, forming shoulders c a, substantially as and V for the purposes hereinset forth.

2. A elevis comprising a bar, A, provided with a bent end, a, a slot, E,and a hole, G, a

bar, B, provided with a slot, F, and a shoul-.

to the bar B, and having a recess, 0, forming shoulders c a, engagingthe end a of bar A,

and a spring, as at D, fixed to bar B, and acting on the cross-piece eof bar A to hold it to the shoulder f substantially as described, forthe purposes set forth.

4. In a elevis, the bars A B, linked together by cross-pieces e f,formed by slotting the respective bars verticall y and horizontally, asat E F, and said bar B having a shoulder, as at f with which thecross-piece e of bar A engages, substantially as herein set forth.

5. In a elevis, the bars AB, linked together by cross-pieces e f, formedby slotting the respective bars vertically and horizontally, as at E F,and said bar B having a shoulder, as at f", and a spring, as at D,holding the crosspiece e of bar A' into engagement with the shoulder fof bar B, substantially as herein set forth.
